Question
I. 2x2 β 19x + 45 = 0 II.
y2 β 14y + 48 = 0 In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer:Solution
I. 2x2Β β 19x + 45 = 0 => 2x2Β β 10x β 9x + 45 = 0 => 2x(x β 5) β 9(x β 5) = 0 Β => (x β 5) (2x β 9) = 0 => x = 5, 4.5 II. y2Β β 14y + 48 = 0 => y2Β β 8y β 6y + 48 = 0 => y(y β 8) β 6(y β 8) = 0 => (y β 8) (y β 6) = 0 => y = 8, 6 Hence, x < y.
